FLUID-PRESSURE SUCTION APPARATUS.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed April 1'7, 1913. Serial No. 761,679.

To all whom it may concern:

Be it known that 1, JOHN R. SOI-IHADER, a. citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fluid- Pressure Suction Apparatus; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enableothers skilled 111 the art to which it' appertains to make and use the same.

My invention relates to improvements in fluid pressure suction apparatus, and is adapted for use with water, steam, gas or any, other pressure medium capable of pro ducing a vacuum when issuing from an inclosed nozzle, such as needed for vacuum otherwise improve on suction apparatus as heretofore constructed.

To these ends the invention consists in providinga suction apparatus with a double air inlet to increase the vacuum and provide free admission of the dust and dirt charged air thereinto; and it also consists in the novel features of arrangement and construction to be hereinafter described-and particularly pointed out in the subjoined claims.

To more particularly describe my improved apparatus, reference is had to the accompanying drawing illustrating the same in which,

' Figure 1 represents a vertical sectional view of myimproved apparatus.

Fig. 2 is a section taken on a plane indicated by line 22, Fig. 1.

Fig. 3 is a cross section taken on line 33, Fig. 2.

A designates the body-portion of the apparatus which is preferably tubular and has its lower end bent, as at B, to form a diffusing chamber having deflecting surfaces C against which the water passing through the body portion strikes and which surfaces cause the stream of water to become broken up and thus occupy the entire cross sectional area. of the body portion so as to prevent the entrance of air thereinto, which would otherwise destroy the suction within the apparatus.

Located at the upper end of the body portion is a pressure-nozzleD which is adjustable within a nipple E fitting into the body portion and preferably soldered thereto, as at e. The nozzle, after being adjusted to bring the discharge end thereof to the desired point within the body portion, is locked in positionby a jam nut F threaded onto said nozzle and impinging against the upper end of the nipple. While this is the preferred form of connecting the nozzle D to the body portion and adjusting the same, it is apparent that any other arrangement for adjustably retaining the nozzle within the body portion may be resorted to.

The body portion is restricted at a'point a short distance below the discharge end of the nozzle D, as at G, so that when the water issuing through the nozzle passes through the throat thus formed, the suction created by the water issuing from the nozzle is maintained at a point beneath the air tubes H which are connected to the body portion of the apparatus at points in line with the discharge end of the nozzle, said air tubes providing two air inlets h for the body portion and being preferably continued in semi-circular form from opposite sides. of said body portion to meet at a'common point I, from which point a single tube J .is led for connection thereto of a hose forming part of a cleaningapparatus.

The air tubes H may well be termed suction-tubes". since the water or other pressure medium issuing from the nozzle D creates a vacuum. which causes the dust and dirt charged air to be drawn therein from a cleaning implement or tool'adapted to be attached through the medium of a hose or the like to the upper end of the tube J, whereit is discharged through the body portion of the apparatus with the water or other pressure medium passing therethrough.

The suction tubes are arranged at a slight angle tothe body-portion A so that the apparatus! may be easily connected to a faucet, or to pipe of the water system, by means of a coupling K carried on the upper end of the nozzle D D, as best shown in Fig. 1.

By providing two dust inlets, the vacuum within the cleaning apparatus connected to the suction tubes H is greatly increased and by making the pressure-nozzle adjustable with reference to the air inlets, the effectiveness of the apparatus can be maintained regardless of the pressure of the water or other 1 medium issuing from the nozzle.

By thus constructing the device a tubular member of circular formation is provided having at one point a tubular inlet for the dust or dirt, and at a diametrically opposite point being connected to the body portion of the apparatus at the point where the pressure nozzle D enters said body portion.

In the body-portion of the apparatus between the nozzle D and the first deflecting surface C in the path of the water passing through said body-portion I provide an air breaker L in the form of a spider which is shown integral with said body-portion, but may be separate and held in position in any approved manner. This air breaker is best shown in Fig. 3 and comprises the central or hub portion M and radial arms N extending to the cylindrical wall of said body-portion, thus providing a plurality of passages 0 through which the water and dirt may pass. Experiments have shown this air breaker to greately increase the efficiency of the apparatus, as it tends to diifuse the water passing through the apparatus and thus prevent the admission of air above this point. This is a very desirable feature of the invention when the pressure of water is below normal, as in such cases the de fleeting surfaces C may not entirely prevent the admission of air into the apparatus.

Having thus described my invention, what I claim is,

1. A fluid pressure suction apparatus comprising a tubular body-portion having a nozzle extending thereinto and having an air inlet in operative relation to said nozzle, and an air breaker in the path of the water at a point beyond said nozzle comprising a hub portion and a plurality of arms extending from said hub portion to the wall of said body-portion, said air breaker preventing the admission of air above the same.

2. A fluid pressure suction apparatus comprising a tubular body portion having a nozzle threaded into its upper end, a pair of suction tubes having a common inlet and being curved to meet at a common point, said tubes being arranged at an angle to said body portion to permit of attaching said nozzle to a faucet, and a tube connected to said suction tubes at said common point.

3. A fluid pressure suction apparatus comprising a tubular body portion having a nozzle threaded into one end, a circular tubular member connected to said tubular body portion at opposite sides of said nozzle and having an air inlet at a point diametrically opposite said nozzle, and an air breaker in said tubular body portion below said nozzle.

4. Afiuid pressure suction apparatus com prising a hollow body portion having a pres sure nozzle and a hollow circular member connected to said body portion at opposite sides of said nozzle, said hollow circular member having an inlet at a point diametrically opposite said nozzle and said hollow body portion having a restricted passage adjacent said pressure nozzle through which the fluid from said pressure nozzle is directed, and an air breaker in said body portion below said nozzle.

5. A fluid pressure suction apparatus comprising a hollow body portion having a pressure nozzle entering its upper end and a supply tube connected to the outer end of said pressure nozzle, said supply tube, pressure nozzle and hollow body portion having their axes coincident, and a hollow circu lar member arranged at an angle to said body portion and having connection therewith at opposite sides of said pressure nozzle, said hollow circular member having an air inlet at a point diametrically opposite said pressure nozzle.

6. A fluid pressure suction apparatus comprising an endless air tube having an inlet at one point and an outlet at a point directly opposite said inlet, a tubular body portion intersecting said endless air tube at its outlet and having its inlet merging into said outlet, said body portion having a bent lower end providing a difiusing chamber, a pressure nozzle entering the upper end of said body portion at the outlet of said endless air tube, and an air breaker in said body portion between said nozzle and said diffusing chamber.

In testimony whereof, I have affixed my signature in the presence of two subscribing witnesses.
